Forum: feature_films Subject: MPEG2 encoding help

I'm encoding a movie to upload to the archive. I'm encoding at bit rate of 2640 Kbps with a frame size of 480x360 (acutally it's a frame size of 480x480), but the Pixel Aspect Ration is 4:3) at 29.97 Frames/sec. Is this size and bit rate going to be a problem? I've tried to encode at 320 by 240 but the image quality is bad. It even with a very high bit rate. I'm using Sorenson Squeeze it that helps. Any advice would be appreciated.

480x360 mpeg2 is not a legal resolution for dvd or svcd, its probably best to confine yourself to a legal resolution to make it easy for people burning at home. 480x480 is a legal resolution for svcd, though I have seen complaints about it for such material here.

Earlier, I believe you said that the source was mpeg2, why do you need to re-encode it at all? Re-encoding mpeg2 to mpeg2 will introduce additional compression artifacts.

Sorry I wasn't to clear on that the final output will be MPEG2. I'm going from motion JPEG-QuickTime to MPEG2

Scott, what you want to do is encode it to the DVD standard of 720x480. It will make it much easier for folks to convert to a dvd should they choose to do so. I would suggest http://www.videohelp.com for info on encoding and such. Thanks for wanting to contribute!

Yep that's what I did, 720x480 Actually Sorenson Squeeze did it for me. I also dinterlaced the picture. I do that to reduce the artifacting when the server converts it to mpeg4. I also ran it through a couple of filters to lighten the image and reduce noise. Personally I think it looks better than the original.
